It’s also a good idea to try a different HDMI cable if you have a spare one. There are some additional steps you should do to fix both a bad Wifi signal, and a bad or no HDMI signal. Below, I will explain these in step by step detail so you can get your Firestick working properly again.

Firestick Signal Problem (How to Troubleshoot)

As with all electronics from time to time they can have software glitches, or one of the components such as one of the cables can be faulty. There are a few steps you need to do to identify what’s causing the issue and fix it, here’s what they are.

Generally, reset your Firestick and your TV. Next, unplug and plug the HDMI cable back in on both ends to make sure it’s plugged in correctly. Then try a different HDMI cable. After that, make sure your TV is on the right HDMI channel, and if it is then do the steps below.

I’ve provided easy to follow instructions for all of the steps you should do below. Each of these steps can fix the issue so after doing it, see if the signal problem has been resolved. And if not, move on to the next step.

1. Restart your Firestick and restart your TV/display device

The most effective way to fix any issue with electronic devices is to restart them. Therefore, the first thing to do to solve the signal problem on your Firestick is to restart your Firestick and restart your TV or display device. It’s possible your Firestick is plugged into the receiver for a home theater system OR a projector rather than a TV. Whatever device your FireTV stick is plugged into restart it. To restart your Firestick disconnect it from the power. You can either unplug the power cable on your Firestick, or unplug it at the wall outlet. Wait for about 30 seconds, and then plug the power back into it.

To restart your display device such as a TV, or projector disconnect it from the power by unplugging it at the wall outlet. WAit for about 1 minute, then plug it back into the power and turn it back on again.

2. Check the HDMI cable is plugged in all the way on both ends

The HDMI cable sends the video and audio signal from your Firestick to your TV. If there’s an issue with it, it wont send a signal. There are few things to check with the HDMI cable:

  • That it’s connected all the way in on both ends – it can have been bumped on accident.
  • The connectors on both ends aren’t visibly damaged.
  • Blow out the HDMI port and the ends of the HDMI cable, and/or use a very soft brush to gently remove any dust built up.

It’s also a good idea to try a different HDMI cable completely, if you have one laying around, or for another device you have in your home such as a computer.

3. Put your display device on the right HDMI channel

Many display devices such as TV, projectors, and monitors have multiple HDMI ports. They have HDMI1, and HDMI2. If your display device is on the HDMI1 port but your Firestick is plugged into the HDMI2 port then the display device will say no signal.

Use the remote on your TV or projector to select a different HDMI port. You can also have a look at what HDMI port your Firestick is plugged into. It will say in small lettering on the HDMI port what port it is. Such as, HDMI1, or HDMI2. That way you’ll be sure your display device is on the right HDMI channel.

If your display device is on the right HDMI but you still have no signal then move on to the next step.

4. Update the software on your Firestick and your TV

The software on your Firestick and your TV can have a pending update. If the software on your Firestick is up to date but the software on your TV isn’t it can cause a mismatch which will stop your Firestick from displaying a signal.

To update the software on your TV it’s best to Google how to do that. Each TV is slightly different. Generally, it’s located in the settings of your TV, under ‘System’ or something similar. Search for ‘how to update software on ____ TV’. Put your brand of TV instead of ____ such as Sony, Samsung, or LG.

5. Try your Firestick on a different display device

To narrow down what’s causing the signal issue try plugging your Firestick into a different display device. Provided the display device has an HDMI port it will work with your Firestick. Therefore, you can use a computer monitor, or another TV. Many projectors also have an HDMI port.

After doing that, put it on the right HDMI channel such as HDMI1 or HDMI2. And see if your Firestick works on a different device. If it does you can be sure that the issue is with the other display device. The HDMI port may be faulty, or it could be another issue. In that case, it’s generally best to contact your TV manufacturer and see what they recommend to solve this issue.

6. Enable the Firestick in your TV settings (only some TV models)

On some TVs you need to enable the Firestick in the TV settings. When you do that it will ask you to put in your Firestick login credentials. This has been reported to be an issue with some Sony TV models, which can cause a signal error.

To do that you need to use your TV remote to open up the settings on your TV. It varies by TV model but typically you press the menu button. Then look for a setting that says ‘devices’. This will list all the devices connected to your TV.

Your Firestick should be listed there as one of the devices. Select, and then select ‘enable’ or similar. It will then prompt you to put in the login credentials for your Firestick. This is your Amazon username and password. With this particular troubleshooting step it’s difficult to figure out if your TV requires it. However, it’s been reported online that it’s required for some Sony TVs. Refer to the owners manual for your TV. If you don’t have the printed version that came with your TV, in most cases you can find an online version of it by doing a Google search or by using the search function on the official website for your TV brand. For example, something like ‘Sony Bravia owners manual’.

The below steps are to troubleshoot a bad network signal. If the issue you’re having is only with the HDMI signal then don’t do the following 2 steps.

7. Factory reset the network settings on your Firestick

A Firestick has software on it that can have a bug with it. Doing a restart can fix this when it happens but doesn’t fix all issues. So, removing and re-adding the network connection can also remove any glitches in the software that can cause your Firestick to not connect to the network.

To do that go to the settings on your Firestick and then go to:

Network > Your Wi-Fi Network, and then press the menu button to forget the network. After that select ‘add network’ or select your Wi-Fi or ethernet connection from the list of network connections it shows.

8. Restart your WiFi modem

It’s common for WiFi modems to have a temporary issue where the internet connection just doesn’t work at all. Doing a reset of your WiFi modem is almost always recommended when there’s an issue with the WiFi or internet. To do that, unplug the power cable at the back of your WiFi modem, wait for a minute or so, then plug it back in.

Another good way to test it’s working is to check that the internet is working on another device that’s connected to your modem such as a smartphone. This will tell you for sure if there’s a problem with your internet connection or if it’s working fine.

Below are some more specific issues related to the signal on a Firestick, and how to fix them. Some involve the same steps above, and you can skip steps you’ve already done. In other cases they will have unique troubleshooting steps that are only for each specific issue.

Firestick No Signal WiFi

To stream video without interruptions a Firestick needs a stable and relatively strong WiFi signal. There are a few factors that change how strong the WiFi signal is, and a few issues with your WiFi modem, or Firestick that can make the WiFi signal weak. To troubleshoot a weak WiFi signal this is what you should do.

In general, restart your Wi-Fi modem, then reset the network settings on your Firestick device. Next, your Wi-Fi modem may be too far from your Firestick and you should position your Wi-Fi modem closer.

Overall, it’s best to start with the first 2 steps, before moving your WiFi modem. Instructions for how to perform each of these steps are explained at the start of this article. Do step 1, step 7, and step 8.

WiFi routers also have a range, and can only send a strong signal so far. Your WiFi modem may be positioned next to a thick wall or something similar that is stopping it from sending a strong signal. Therefore, moving your WiFi modem a little bit can dramatically change the strength of the WiFi signal.

Testing the WiFi signal is not just on your Firestick

A good way to test this is by using another device connected to the same WiFi network like a smartphone. Walk around the area where your Firestick is to see how strong the WiFi signal is on your smartphone. Also, move the modem a few feet in either direction and do the same thing.

If your smartphone has a really weak WiFi signal as well, then you can be sure its modem. You can get a WiFi booster that you position in between your WiFi modem and another part of your house where you want a WiFi signal. It receives the WiFi signal from your modem, and then boosts it.

There is also an ethernet adapter for a Firestick. This can be used to plug your Firestick into the modem via a cable which is guaranteed to have a strong internet connection. Before doing any of these steps it can be worthwhile contacting your internet service provider. They may be able to provide you with a stronger modem. That may or may not be included in your current internet plan.

Firestick Losing WiFi Signal

A WiFi signal that is working normally will remain on almost all the time. If there’s an issue with the WiFi signal it can be connected one second, and then weaker, or disconnect completely a few moments later. When this occurs it can be related to your Firestick or can be an issue with your Wifi router, in either case this is what you should do to fix your Firestick if it’s losing the WiFi signal often.

As a general rule, first restart your WiFi modem by disconnecting it from the power, and then plug it back in again. After that, reset the network settings on your Firestick. Finally, restart your Firestick by disconnecting the power cable, and plug it back in again.

These steps will solve this issue in most cases. But, your WiFi modem can also be too far from your Firestick. Or, your WiFi modem can be positioned where the signal is much weaker. Moving your WiFi modem even a foot or two can change how strong the WiFi signal is. If your WiFi signal is weak on your Firestick AND on other devices you should contact your internet service provider to have them troubleshoot the issue with you.

Firestick Losing HDMI Signal
